Application filed April 10, 1924. Serial No. 705,665.

This invention relates to improvements in apparatus for burning fuel oiland more particularly to the oil feed mechanism of such apparatus,proposing a construction which i is intended primarily for domestic orhouse heating burners but which may also be emp edto advantage inconnection with any ydiocarbon installation in which the fuel is not ruired to be fed under pressure or but a slight degree of pressure may berequired.

The principal objects of the invention are to provide an ap ar'atuswhich may be roduced and instafied at low cost, whic is 16 simple inconstruction and certain and safe in operation and which issubstantially free from liability to derangement.

With the above objects in view the invention consists generally in aconstruction wherein'the inlet end of the oil supply p1pe projects abovethe normal level of amaintained body of oil which during the operationof the burner is subject to a pressure influence by which the oil levelis raised to 26 a point above said inlet end, thereby permitting'the oilto flow into and through the burner supply pipe; the invention alsoconsists in various novel features of structure and combination employedin. connection with the instrumentalities for producing the operationsabove described.

An embodiment of the invention is illustrated in the accompanying drawinin which the single figure is a view part y in side elevation and artlyin section.

The oil is store in an elevated tank 1 which is connected b a pipe 2 toan .oil feed reservoir 3 in which the supply of oil is maintained at anormal leve indicated by to the broken line X. The reservoir 3 includesa feed chamber 4,-a dischar chamber 5 and a connection 6 between theower ends of the chambers 4 and 5. The chamber 4 is prov1ded at itsbottom with an inlet duct 'I with which the pipe 2 communicates, theduct 7 bein opened and closed by a needle valve 8 whic is controlled bya float 9 and float operated connecting mechanism 10 of an suitableconstruction whereby when the 011 is at the level X the valve 8 is heldclosed and when it falls below such level the valve 8 is opened.

The oil is delivered to the burner (not shown) by a pipe 11 having avertical inlet 011 in the reservoir 3 being escape of air through theextension 12 arranged in the chamber 5 with its upper end suitably abovethe normal oil level X. The effective size of the upper or lntake end ofthe extension 12 may be regulated by a suitable adjustable valve 14.

Air is supplied to the burner'to promote combustion by a suitable bloweror pump 15 which may be driven by an electric motor 16. As shown thepump 15 is formed with an intake chamber 17 having an air admiss1onopening 18. The reservoir 3, 'by virtue of the chambers 4 and 5 and theconnection 6 is, in efl'ect, a U tube and is made operatlvely responsiveto air velocity conditions in the chamber 17 by means of a ipe 19extending between the chamber 1 and the upper portion of the chamber 5.h I111 operat1on the blower 15 draws air at 1g 1 livers it to the burnerthrou h .a trunk 21. A reduction in pressure is t us effected at the fanend terminal of the pipe 19 and by said pipe is transmitted to thechamber 6. i

The suction influence thus created in the chamber 5 during the o rationof the blower is sufiicient to raise t e level of the oil to a pomtabove the upper end of the extension 6 and under such conditions the oiloverflows into said extension and thence passes by the pipe 11 to theburner, the supply of automatically regulated and maintained b the floatcontroHed valve 8 in the well hnown manner.

The pipe 11 is provided at a point near the reservoir 3 with a U-shapedtrap 20, the purpose of which is to maintain a constant oil seal whichis effective to prevent the (pipe 11 into the chamber 5, thereby to avoiimpairment of the suction influence maintained in said chamber duringthe operation ofthe blower and to provide for certainty in the operationof the burner.

When the operation of the blower is discontinued atmos heric pressureconditions are re-establishe in the pipe 19 and chamber 5 with theresult that the oil returns to its normal level X and the flow of oil tothe burner throu h the pipe 11 is discontinued, the oil seal, owever,being maintained by the tra 20 whereby the operation may be resumemerely by starting the blower.- The system is thus adapted either forthe steady or intermittent operation of the burner, the

velocity into the chamber 17 and deair and oil. feed being soco-ordinated that danger is in any case avoided.

The system may of course have any desired capacity within a considerablerange, the rate of flow of the oil being determined by the setting ofthe valve 14 and the air supply to the burner being variable accordin tothe size of the opening 18.

aving fully described my invention, I claim:

1. In an oil burning apparatus, in combination, an oil feed pipe toconduct oil to the burner, an oil tank, an oil reservoir int-crposedbetween the feed pipe and the tank and comprisin two chambers connectedat their lower en s, the reservoir thereby functionin as a. U-tube,means for maintaining the oi at a normal level in the reservoir,v

means for creating a suction influence in one of said chambers, therebyto change the oil.

level, an extension of the feed pipe into which oil flows from said lastnamed chamher during the operation of said means, and

strap in the feed pipe to create an oil seal.

2. In an oil burning apparatus, in combination, an oil feed pipe toconduct oil to the burner, an oil tank, an oil reservoir interposedbetween the feed pipe and the tank and comprising two chambers connectedat their lower ends, said reservoir thereby functionin as a U tube,means for maintaining the oi at a normal level in the reservoir, ablower to supply air to the burner, a connection between the blower andone of the chambers of the reservoir whereby the blower during its airsupplying operation" creates a suction influence in sai chamber, the oillevel being thereby changed, an extension'of the feed pipe into whichoil flows from said chamber during the operation of the blower and atrap in the feed pipe to create an 011 seal. 3. In an oil burningapparatus, in combination, an oil reservoir aving two chambers connectedat their lower ends, an oil tank connected to one of the chambers, floatfeed mechanism in said chamber to maintain the oil in the reservoir at anormal level, an oil feed pipe having an upward extension in the otherchamber, said extension terminating at a point above the normal oillevel, a blower to supply'air to the'burner,

and a connection between the blower and the chamber with which theextension communicates to create a suction influence in said chamber andthereby raise the level of the oil'to a point above said extension.

4. In an oil burning apparatus, in combination, an oil reservoir havingtwo chambers connected at their lower ends, an oil tank connected tooneof the chambers. float feed mechanism in said chamber to maintain theoil in the reservoir at a normal level,

in the other chamber, sai extension teran oil feed pipe having an u wardextension" minating at a point above the normal oil level, a blower tosuppl air to the burner,

a connection between t e blower and the chamber with which the extensioncommunic ates to create a suction influencein said chamber and therebyraise the level of the oil to a oint above said extension, and a trap int e oil feed pipe to create an oil seal.

5. In an oil burning appartus, in -com-' binat-ion. an oil tank, anoilreservoir supplied by the tank, automatic means for mamtaining theoil at a normal level in the reservoir. an oil feed pipe communicatingwith the reservoir with its inlet end at a point above the normal oillevel whereby upon the'oil level being sufliciently raised oil'may flowby gravity into and through said pipe,

a blower to sup 1y air to aburner, and a pipe connection tween theintake side of the blower and the reservoir to transmit suctioninfluence to the reservoir, thereby to raise the oil above the leveldetermined by said automatic means and to a point where the oil flows bygravity into and through the oil feed pipe. t
